Well, definitely take France with at least 1 inf.
Whether or not to go heavy into Western depends on what Germany has to counterattack with. It’s a very complicated question, but ultimately it comes down to this–if Germany can easily trounce any army you land there with enough force that he kills all your stuff and you can’t counterattack, then don’t land there. But if you can hold it, or at least make Germany pay dearly to retake it (and set-up another counter of your own), then its often a good move to land in force, since the resulting battles will weaken Germany.
